3-78 Chapter 3: Installing Optional Hardware Features
Installing Additional Ports
When a touch screen device such as the 5963 12.1" Touch Screen or the
5953 12.1" DynaKey with touch screen is attached to the Series 4xxx
Motherboard, serial port C is consumed. Therefore, if the configuration
has a UPS and a touch screen device, only the two RS-232 ports on the
Motherboard are available. Ports can be added to the workstation. Kit
7452-K156 can be used to add a parallel port and an RS-232 port to a
Series 4xxx Motherboard.
Also described in a following section is kit 3030-K169 which can be
used to add four RS-232 ports to a 7452.
